Cassandra and OpsCenter has a range of backup and restore topics. I will start with a basic overview of Cassandra backup/restore, walking through the operational steps to provide the understanding required to perform an on disk backup and restore. Expanding on this overview, I'll cover the limitations (including schema requirements) and their impact on the restore process. Further, I'll discuss commit log archiving and point in time restore operations. After covering the underlying operations, I'll wrap up with a discussion of how OpsCenter automates this process and leverages S3.
